Update on SSM-53801

[HeyBales]

Wow. So I had my battery replaced for the second time last December (flooded.)
Three weeks ago, I got the battery saver notifications on my app and the lights would not come on inside. I took it in and they flashed the ACCM module, charged the battery and told me the battery was good.
I was thinking, "great, 3 yr warranty expires the end of this month and this is just going to happen again in three months - past warranty."
"Luckily" it happened again last week! This time they flashed the TCU. It took several attempts before it accepted the new programming. This time when the battery was tested, it was at 38%. They replaced it with a new AGM battery.
Whew! Squeaked it in before the warranty expired!

That's my plan!
I'm expecting to perhaps need to play the radio for some extended time in the final month to help encourage the needed result.

Except I wasn't expecting they might make the upgrade to AGM possible.

Perhaps by my end of 3 yrs they'll have an update for the BMS!
And the ICE will be replaced by unicorn power!

After 3 battery replacements in 14mo and the ACC SSM updated last May i was left dead again this week after only 1 day idle. Truck spent 3 days at Ford and Ford Customer Care acknowledged Hybrids have an issue and approved a replacement to an AGM ( i have been asking for a year) at No Charge. I am happy i now have AGM battery. Do i think my issues with parasitic draw are over? Not a chance which is what i told the service manager.

There is now a class action lawsuit for bad batteries.
Along with others on the Maverick.

Isn't Camel the bad FLA batteries used in a short run of EB models?

At least that recall happened after they determined it was a bad battery.
But that too had a software update first to try to get better at seeing a potential battery issue so the auto start/stop would be disabled before you got stranded in a bad spot.

I'm betting the defective engine one is requiring a lot more logging of what serial number part went where.
I'd still like to hear the inside scoop on that one - surely they logged that already. Did someone delete a file, supplied lost it, how long a run was the potential bearing issue there, besides the truck run dates assembled.
Maybe that lawsuit will bring out those details.

I got my truck in August 23, by October they replaced with NAPA AGM battery and the discharged battery issue continues.

So yours was the great example of another possible issue for DSM - recharged battery was actually testing fine, but the TCU with stuck value is telling Ford it's not, and turning the modem off.

But you are saying after that fix, it's back to problem state?

So unless your TCU likes getting stuck with a low value - do you have a multimeter to actually see what the morning resting voltage is - is it actually low?
Is it actually discharged/drained (that would mean it can't start truck), or merely undercharged like most of us?
Obviously not the 14 days reason for DSM - unless truck can't count.
That would be below 9.5 V if purely a voltage reason.
The trucks PID for SOC% more difficult to get, but it seems below 40% is other reason, and the prior cause you had DSM.

My hybrid lariat 2022 vin # is in the range of the "possible ice failure" long block replacement IF ONE OR BOTH CODES of two which were added show up when truck is having problem. If I remember correctly it is warranty for 10yr/150k miles. Seems like it was limited to some 2022 and maybe a very few 2023's. This is related to the ones that had the air dam/shield holes done and the lower radiator shutters removed.

Got my truck back on Sept 24th after the completed the ACCM update (per the latest TSB that is trying to fix this) and had the 'remote features disabled l' message pop up on the phone application the very next day, and every other day after that. As part of the CAMVAP arbitration process you must have attempted to address the problem directly with the manufacturer (in addition to the dealership). So today I spoke with Ford Canada, who initially said that without a proper diagnosis they can't do anything. I explained that for more than a year and a half they have not diagnosed the problem and have only made guesses to try and fix it, to no avail. It was then he reported he would reach out to my dealership to investigate further. They asked what resolve I was seeking, I told them I wanted them to buy back my vehicle, because there is no fix in site. They told me to stay tuned. I personally think that every person experiencing this issue needs to escalate it directly with Ford Motor Company and file a claim with CAMVAP (For Canada residents) or identify the appropriate process under your state's Lemon Law (https://bbbprograms.org/programs/all-programs/bbb-autoline/lemon-laws-by-state)

I suspect Ford is attempting to avoid these programs by holding people off until their manufacture's warranty expires or you are past the number of Kms to allow for the matter to be arbitrated

planning to pick up lariat this week

Fresh off the production line

I love to see what battery was installed AGM or not.

So leery about all these problems

All 2025 Hybrids now come equippped with AGM 12V batteries. But, will eventually have the problem (battery drain/poor state of charge) if it is still there. It seems, some vehicles do not experience these problems.

 

[ZABSMAV]

Have heard this before. So far, it seems some vehicles may have had the drain addressed by the SSM, but for many it changes nothing.

Exactly same here. Ford needs to try again and stop guessing.

Yep. Perhaps some of the electronic non air gap switches leak a little current in the "off" position and some don't.

Early on, some of us had issues due to faulty fuses under the hood. One of mine was replaced in 2023, because it was cracked. Other users reported the same fuse was replaced. This was tested on trucks with the poorly manufactured 12v battery charging cable. I have to wonder if this fuse is still a problem.

When one Ford tech worked on battery cable issue, he noted how poorly designed the 12v battery charging system was designed. It had corrosion and dirt all over it, on a 6 month old truck. Looks like a maintenance nightmare in the video.

Hit or miss problems could easily be caused by the fuze or similar issue. Wish under hood fuzes were more easily accessible.

That's my plan!
I'm expecting to perhaps need to play the radio for some extended time in the final month to help encourage the needed result.

Well I have officially joined the club of power drain issues. My 2023 Mac hybrid battery is dying within 24 hours of being parked even after long drives. Took it to the dealer to try the ssm 53801 fix which they did and said my battery was fine on load test. They charged my battery to 97 percent and told me to pick up the truck. By the end of the day the charge had dropped to 37% while in their lot and I got a message on the app. Now they say they will change the battery but I suspect the same thing is going to happen as the parasitic draw is clearly not fixed. Ugh. They also said they wouldn't put in an AGM battery because Ford only allows a FLA replacement. What now??
